Simple Answer: Yes, we have configured the "Sign In Station" to be response to tablets and mobile devices using Android, Apple, or Windows operating systems/browsers.
Techie Answer: Yes, the Front End Web Developer applied Bootstrap 3.0 to the "Sign In Station" as of May 6, 2014 so all "Sign In Stations" after that date will be auto-magically responsive to the browser size. We have tested it on an iPad 2, iPhone, and several Android devices. Frankly, the "Sign In Station" has always worked on any of these devices since all this technology is browser based.
NOTE: Whichever device MUST have Internet access and be connected to work.
